I also decided to make versions for lower voice (per voce basso) which could be a tenor or a baritone, and for bass voice (per voce contrabasso), not surpassing the c' limit for performance by those male singers who have real difficulty with really high notes (like me...).
This necessitated changes in the accompaniment. In the instrumental recordings the basso voice is aliased by the dulcian, the contrabasso voice by the trombone.

There now are three versions: 1 for soprano/alto, 1 for tenor/baritone and 1 for basso.
1. Per voce superior (alias oboe), accordion, trombe da tirarsi, theorbo, cornetto and horn in F.
